Can I set an image as background (Make Live Titles transparent) on Lumia 735?

I want to buy the Lumia 735 but I haven't seen anyone with the transparent titles. I know it runs the Windows Phone 8.1 but I'm not sure if it has that option. I have the Lumia 520 and I can change the background image. Will I have to install Preview for Developers or something? Thank you!
